Poster Child is Asher Blum (drums), Mae Weaver (vocals), Wyatt Crossan (bass), and Finn Vora (guitar).

The idea of the band started in August of 2021 while Asher and Finn were on tour with Jon Anderson of Yes and the Paul Green Rock Academy. Throughout the next year, they started jamming and writing, eventually bringing in local bassist Wyatt Crossan and PGRA singer Mae Weaver to round out the lineup.

The band hit the ground running with a show at the Kelly Center in Havertown after only two rehearsals. Since then, they have developed a multi-faceted rock and pop sound that blends genres and ideas, allowing them to cater to a wide variety of audiences and venues.
